The estimated lengths are 12in. and 5 in. This would be an estimated difference of 7in.
The estimated difference is going to be higher than the actual difference because in rounding 11.7 to 12, you are losing .30in, but in rounding down 5.25 to 5, you are actually gaining .75in.
The ACTUAL difference is 6.45in
Let a be the bigger number and b the smaller.
So a-b=44
and a^2+b=376376
(44+b)^2+b=376376
b^2+89b -374440=0
Solve for b and you get a. Are you sure it is 376376 not 376?
The answer is b, 5x^2 + 24x + 1
Answer:
I answered it as C, but the correct answer is B :)
